How silly the Telerik DataAccess wizard is.

gistfile1.cs

// in the generated massive file for fluent mappings.
	
	public partial class FluentModel : OpenAccessContext, IFluentModelUnitOfWork
	{
		private static string connectionStringName = @"AdventureWorksConnection";

		private static BackendConfiguration backend = GetBackendConfiguration();

// The line below is generated by the Telerik 'wizard' (which should actually be called 'dumbass') and causes the code to recreate the mapping model
// every time.
		//private static MetadataSource metadataSource = new FluentModelMetadataSource();

// using this line however fixes it (ref: http://docs.telerik.com/data-access/developers-guide/code-only-mapping/getting-started/fluent-mapping-creating-custom-context )
// and makes the individual fetches at least normal, as they otherwise would be massively slow. It does have the disadvantage that the model can't
// be changed at runtime, but in that case, one would probably use a separate model instance for that situation anyway.
		private static MetadataContainer metadataSource = new FluentModelMetadataSource().GetModel();
// rest stays the same
